This summer, there has been another bumper harvest of grain, and the post harvest links of grain storage, circulation, trade, and processing across the country have reached a peak period. Through the Jilin-1 satellite, take a panoramic view of grain trade and circulation ports and docks, and see the busy scene there. The super "storage box" intelligent management of 8000 tons of grain has just seen the busy grain transportation scenes in ports and docks around the world this summer from a satellite perspective. In addition to grain circulation, grain collection and storage are also important links in ensuring food security. Next, we will follow the camera of the CCTV reporter and go to Wuxi, Jiangsu to see how the National Grain Reserve manages 8000 tons of grain? Do you think this place looks like a digital studio now? It's actually a grain depot, named Jiangsu Wuxi National Grain Reserve. The normal storage capacity of this warehouse is 8000 tons of grain. How is this 8000 tons of grain managed safely and effectively? It's simple, everyone, you can see it clearly through the big digital screen in front of you. Gao Zhihang, a senior engineer at COFCO Wuxi Warehousing and Logistics Department, introduced that these 8000 tons of grain are stored in 11 layers, with each ton of grain being a pallet and a square on the screen. There are a total of 8000 squares in these 11 layers with independent numbers and their own "identity files". The permanent population of Wuxi is around 5.5 million. Based on the daily basic food needs of each person, a storage capacity of 8000 tons can ensure the basic food supply for Wuxi's permanent population for two weeks. However, these food supplies are not all put into the market at once. The key to "locking" and "preserving" stored grain is precise temperature control. The first feeling upon entering the low-temperature warehouse is that it quickly transitions from scorching heat to cool air, reducing the temperature by at least half compared to the outside. In the summer season, when the reporter walked into the low-temperature warehouse, he first felt that the temperature was quite low. How many exactly are there? Let's take a look, the current temperature in this warehouse is around 18 degrees Celsius, and the humidity is between 67% and 68%. For us, a slightly lower temperature is the most suitable for these rice varieties, but will the taste of the rice after being stored for a period of time change after it is launched? Gao Zhihang, a senior engineer at COFCO Wuxi Warehousing and Logistics Department, introduced that keeping rice in a low temperature state during storage can preserve and lock freshness. The taste is almost identical to that of new rice, which is the biggest function of the low-temperature storage. The 8000 ton autonomous temperature controlled intelligent three-dimensional warehouse does not require too many workers, and the entire grain warehouse can be easily managed by only three or four people. Less manual handling, more 'digital tools'. On the 11th floor three-dimensional shelves of the grain depot, each stack of grain has a unique code. The fast and intelligent cloud grain warehouse realizes the modernization of "warehouse roaming" and the high-tech way of "opening" the grain warehouse is not limited to this one. At the Shazhou Central Grain Depot in Zhangjiagang, Jiangsu, the digital service platform has made it faster to inspect the depot points. Next, I will go on a "warehouse area tour" with the reporter. A small thing can tell you how convenient it is. For example, the entire grain depot covers an area of nearly 150 acres. If you walk with your legs to see the entire depot, it may take more than an hour. But now, if you hand it over to "warehouse roaming", you can quickly complete this task. The core functions of the grain data intelligence integration service platform are composed of several sections, including warehouse roaming, online inspection, grain situation cloud map, and pest warning. Through high-definition intelligent cameras and sensors scattered throughout the grain depot, we provide precise services to every grain depot and every grain. For example, the change in grain temperature can be seen from the comparison chart of the "three primary colors" of green, yellow, and red in front of us. Grain is a living organism that has temperature and can breathe. For grain depots in the midst of summer, administrators not only need to constantly monitor the temperature and humidity changes of the grains, but also be alert to the various pests listed on the digital screen. However, these do not require much effort and can be assisted by intelligent assistants. It is reported that the Shazhou Central Warehouse has collected more than ten green grain storage technologies, among which five are related to temperature control, with clever techniques for sun protection, insulation, and cooling. Take the bungalow warehouse in front of us as an example. The roof, floor, four walls, and six sides of the warehouse have been insulated, just like putting a "cooling suit" on the granary, making it a true "cooling warehouse". According to a special survey by the Food and Agriculture Organization of the United Nations, about 14% of global food is lost in the supply chain from harvest to retail due to the busy use of green warehousing for quality preservation and food conservation. During the 14th Five Year Plan period, China continued to carry out grain conservation actions, vigorously promoting the application of green grain storage and other technologies, accelerating the implementation of green grain storage improvement actions, and promoting grain conservation and loss reduction throughout the entire chain. Since the 14th Five Year Plan, China has made significant technological breakthroughs in the integration and industrialization demonstration of key technologies for post harvest storage, quality reduction, and green intelligent warehousing of grain, as well as in the logistics, warehousing, and allocation of emergency supplies. China has built and upgraded warehouses with a capacity of over 65 million tons, and the green storage efficiency and performance of grain warehouses are constantly improving. By increasing investment and promoting the construction of storage facilities, a grain collection and storage guarantee system that is compatible with grain production, storage, and circulation has been basically formed. As of now, there are a total of 200 million tons of low-temperature and quasi low-temperature grain storage warehouses and 55 million tons of controlled atmosphere grain storage warehouses in China. The comprehensive loss rate of state-owned grain depots during the grain storage cycle is controlled within a reasonable range of 1%. While ensuring the safety of food quantity, the level of quality and freshness preservation has been further improved. (New Society)
